Error: sls dynamodb install not working

Serverless command "dynamodb" not found means the DynamoDB plugin was not loaded. If the command exists but installation fails, investigate the download, Java runtime and local filesystem instead.

1. Run the command from the service directory that contains serverless.yml. Verify dependencies are installed for that project and use its local Serverless CLI.
2. Replace the old serverless-dynamodb-local plugin with serverless-dynamodb and update the plugins list. Do not keep both enabled.
3. For the Java installation, use JRE 17 or newer for current DynamoDB Local and check java -version. Inspect the installation error for download, certificate or directory-permission failures.
4. The successor plugin README lists Serverless v1 through v3. Check your Framework version's compatibility before depending on the plugin; direct Docker setup avoids that integration.

npm uninstall serverless-dynamodb-local
npm install --save-dev serverless-dynamodb

plugins:
  - serverless-dynamodb
  - serverless-offline

java -version
npx serverless dynamodb install
npx serverless dynamodb start

Place serverless-offline after the DynamoDB plugin when using both. An alternative without a Serverless plugin is:

docker run --rm -p 127.0.0.1:8000:8000 amazon/dynamodb-local:3.3.2

Point the application at http://localhost:8000 with a Region and dummy local-only credentials. Installation and starting the database do not automatically configure your application endpoint.

See local setup instructions and the maintained plugin README.
